Jimi Jamison, the lead singer of rock band Survivor, died of a heart attack at the age of 63, the band said. The group posted a tweet Monday, mourning Jamison and offering thoughts and prayers to his family and friends.

Jamison’s booking agent told TMZ Monday the singer died of a heart attack at his Memphis home. Jamison was reportedly found in home around 1 a.m. by his son.

Jamison joined Survivor in 1984 after it released its hit song “Eye of the Tiger.” He spent many years as the band’s lead singer, contributing his vocals to a number of Survivor songs including “The Search is Over,” “Is This Love” and “Burning Heart” from “Rocky IV.”

During his solo career, Jamison sang and co-wrote the “Baywatch” theme, “I’m Always Here.”

“The family has asked for privacy during this extremely difficult time,” Jamison family attorney Jeff Ward said in a prepared statement to WMC, Memphis. “In lieu of any demonstrations of sympathy, the family has requested that donations be made to Jimi's favorite charity, St. Jude's Children's Research Hospital.”
